From 2ffc9cc1917b1bb6fe86881a94a47dce9aa15168 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Wed, 19 Aug 2009 20:49:49 +0200 Subject: change database file names With very deeply nested devices, We can not use a single file name to carry an entire DEVPATH. Use : as the database filename, which should also simplify the handling of devices moving around, as these values will not change but still be unique. For the name stack we use the : now as the filename. > On Tue, Aug 18, 2009 at 09:59:56AM -0400, Ric Wheeler wrote: > The first is that udev grumbles during boot about "file name too long" > like the following: > > Aug 17 06:49:58 megadeth udevd-event[20447]: unable to create db file > '/dev/.udev/db/\x2fdevices\x2fpci0000:00\x2f0000:00:04.0\x2f0000:17:00.0\x2f0000:18:0a.0\x2f0000:1f:00.0\x2fhost11\x2fport-11:0\x2fexpander-11:0\x2fport-11:0:0\x2fexpander-11:1\x2fport-11:1:0\x2fexpander-11:2\x2fport-11:2:17\x2fexpander-11:3\x2fport-11:3:1\x2fend_device-11:3:1\x2fbsg\x2fend_device-11:3:1': > File name too long --- TODO | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'TODO') diff --git a/TODO b/TODO index 6a475365be..5df63fad05 100644 --- a/TODO +++ b/TODO @@ -1,4 +1,12 @@ + o drop support for node names in name stack, support only symlinks + With well defined and kernel-supplied node names, we no longer need + to support a possible stack of conflicting symlinks and node names. + From there on, only symlinks with identical names can be claimed + by multiple devices.
